塑料管道国内外技术发展新动向(Ⅱ)

New Development of Technology for Plastics Pipe System

介绍了各个应用领域塑料管道系统近年技术发展的新动向。PVC-M能显著提高韧性又可以节约材料,为聚氯乙烯压力管道系统的发展开拓了新机遇。聚乙烯管道系统在不开挖铺设和水中铺设等领域应用日益广泛。各种增强复合管道系统成为发展的热点。毛细管垫表面调温系统等有利环境保护的新技术扩大了建筑内塑料管道系统的市场。

New developments of technology for plastics pipe system in various applications were introduced. PVC-M pipes （modified PVC pipes） improved the toughness and saved the amount of the materials, as well as they created the new opportunities for PVC pressure pipe systems. The applications for submarine and trenehless installation of PE pipe were widely used. There was a focus on the reinforced thermoplastic pipes （RTP）and composite pipes. The surface regulation systems, such as capillary tubing mats, in favor of environment were expanded in the market of plastics pipes for building.
